Duplicating another trader’s positions (or having one’s positions duplicated) so that identical trades appear across multiple accounts — ‘trading in concert’.
The rule
Duplicating another trader’s positions (or having one’s positions duplicated) so that identical trades appear across multiple accounts — ‘trading in concert’.
In denialrate’s refusal-ground taxonomy this category maps to a prohibited-conduct rule — a rule that bars a specific behaviour outright (cross-account hedging, latency arbitrage, copy trading). The ground tells a trader which kind of clause to look for in a firm’s terms: a process rule, a risk rule, a prohibited-conduct rule, a KYC rule, or a discretionary right the firm reserves to itself.
Industry-estimate share
Industry estimate: 12% of prop-firm payout denials. industry estimate, source: hftarbitrageplatform.com, accessed 2026-08-03. This is an industry estimate, not a denialrate measurement; denialrate adopts the taxonomy and publishes its own per-firm, per-category counts as the verified-cases ledger fills.
Firms affected
Firms whose published terms or recorded controversy reference this category. This is a keyword match against the firm’s denial clauses and controversy ledger, not a verified classification — treat it as a pointer, and check the dossier for the source text.
Verified cases across firms
0 verified cases in this category. A verified case is a denied-payout report denialrate has checked against a primary source (the firm’s terms, a court filing, a regulator notice). Trader reports alone never count as a verified case.
